In this tutorial we will check how to read content from a file using the SPIFFS file system of the ESP32, running the Arduino core. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board. Introduction In this tut

For those of you experienced working with C or C++ already (which, after you read through the sections on openFrameworks, will be all of you), you’ll recognize the .h file and what it does. The .h file is what is imported into the Arduino application, using the #include statement. ...
然后一个简短的项目介绍,ReadMe吧~ 一个是实物连接图 一个是电路图 这个是程序框架 小灯闪烁,这个LED在13jio~,就是浪费掉了其实,完全可以引出来再用 这个也简单 在code的最上面指定了按下的按钮的引脚号,设置它的模式 然后代码和上面的一样 我们也可以看看这个ISP就是烧写AVR芯片进Bootloader,出现了这个Arduino...
